Function displays
The six LEDs on the front panel of the valve coupler display the present channel or
valve coupler status. The following table shows the LED functions:

Fault elimination, repair
No changes must be made on devices to be operated in certified hazardous areas.
Repairs to the device must only be carried out by specially trained Pepperl+Fuchs
technicians.
Function monitoring
The valve control outputs of the valve coupler can also be checked for correct
functioning without connected valves by simulating the valve by a 3 kΩ resistor. In de-
activated state a voltage of approx. 0. 3V and in activated state a voltage of approx.
3 V can be measured via this resistor. It is not possible to connect a voltmeter directly
to the open terminals of the valve output because then a voltage of 6 .8V ... 7.4V is
measured independently of the state.
Subject to reasonable modifications due to technical advances.
